Miles from Nowhere S01E12 - Continuing the Line

Episode Overview

The series finale explores how different species achieve their primary mission of passing on their genetic legacy. This challenge has led to a myriad of unique adaptations. For instance, barnacles, despite their immobility, possess both male and female reproductive cells, making any neighboring barnacle a potential mate. In contrast, a female elephant endures an extensive 22-month gestation, carefully selecting a strong male to father her calf. Meanwhile, a female chinchilla employs a drastic rejection method, squirting urine at unwanted suitors. Mating can be perilous, as seen with a cautious male tarantula that must evade her venomous fangs before proceeding. Timing is crucial for some, like male crabs, who can only mate when a female has recently shed her shell. Male sea lions fiercely compete for a harem, with some resorting to stealing reluctant females. Attenborough notes that human monogamy is quite rare in the animal realm
